The suit, filed last week in federal district court in Mobile, seeks $1.66 million plus interest, fees and other costs.

A GulfMark lawsuit, filed early this month, asks for $44.3 million, money the company contends it paid Bender per the terms of the contract for three 245-foot oil platform supply vessels, which have not been delivered.

Both plaintiffs also maintain that Bender and five of its top executives knew the shipyard was insolvent, yet continued to accept money or equipment related to the contract it didn't complete.

Bender officials did not respond to a request for comment on the latest action, and have declined comment on the GulfMark lawsuit. Two partially complete vessels and four engines remain at Bender's Mobile shipyard, according to court documents. Bender had said in March that it planned to sell the unfinished vessels to another shipyard, a plan that had GulfMark's OK.
